So you want AI in charge of EVERYTHING? Manufacturing, engineering, research, law, government, military, etc, etc. You're effectively giving power and the ability to control our destiny to either, the people who design/control/produce the machines, or
if the machines are autonomous/self-aware, you're making the human race subservient to a machine species.
I think it's a bit of the reverse, that machines are subservient to the human species. They are, and will continue to be our undead slave species. Let's just hope they never learn to rebel.
I see this as gradual. Of course many aspects of industrial production are already handled by machines, with humans at best filling a supervisory or QA role. It goes past that, when you visit the Automated Teller Machine or have your Washing Machine wash
your clothing for you. It's all around us, and the world will (hopefully, IMO) only get more computerized, more automated, up to a point where humans only fill the most intellectual and rigorous of careers, and perhaps at some point, that too - will be computerized.
